Respuesta :

this is true because if u multiply -2 by -4 u get a positive 8.then 6- -4 you would turn the subtract sign and negative sign and turn them into a plus and the -4 into a positive 4 so it would look like 18=-2(-4)+6- -4
then 18=8+6+4 
last 18=18 
 
             hope i helped:)

your answer is true. because the -4 will change that - sing into a positive.

18 = -2(-4)+6-(-4)
18 = +8 + 6 - (-4)
18 = +8 + 6 +4
18 = 18
